Radiocarbon dating has confirmed that human habitation of Grenada dates back at least two millennia. The original inhabitants were Arawak, who migrated north from the Orinoco River basin in South America, as evidenced by the style of the petroglyphs and stone tools they left behind. Alas, we know little more about them, because they were replaced by the Kalinago people, who were then decimated by the French in the 17th century. Nor does it help that archaeologists have given Grenada relatively limited attention, or that the government makes little effort to preserve what remains.
